Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0019] Example: An auxiliary device for prenatal pelvic floor muscle exercises in postpartum women, including a device frame 1, as shown in the attached document. Figure 1 As shown, the instrument rack 1 is equipped with a main support rod 2, and symmetrical knee supports 3 are mounted on the main support rod 2, as shown in the attached diagram. Figure 2As shown, the knee frame 3 comprises a base 16 provided on the main support rod 2, one end of the base 16 is provided with a baffle 17, and a magic tape band 18 is also installed on the base 16. The base is a planar support structure, providing a stable knee supporting surface, ensuring the support of the kneeling posture of the puerpera, and the end of the base is provided with a vertical baffle to form a physical limiting structure, which can block the sliding of the legs forward during exercise. The surface of the base is equipped with a magic tape band, the length of which can be flexibly adjusted, and can be matched according to the leg circumference of the puerpera, and the magic tape is firmly connected and convenient to detach. In order to protect the knees of the puerpera, a sponge layer is covered on the baffle and the base. The handrails 4 are installed on both sides of the equipment rack 1, and the handrails 4 comprise a main rod 19 provided on the equipment rack 1, and the upper end of the main rod 19 has a rubber sleeve 20. The main rod 19 and the equipment rack 1 have a lateral support rod 21. Due to the protrusion of the abdomen during pregnancy, the body center of gravity moves forward, and when performing pelvic floor muscle exercise (such as buttock up and down anal movement), the body is easy to shake and the posture is unbalanced. When the puerpera holds the main rod with both hands, the body center of gravity can be adjusted with the help of the support force of the handrail to offset the imbalance caused by the buttock movement; the end of the main support rod 2 is provided with a stand 5, the stand 5 is provided with a top cross bar 6, and the top cross bar 6 is provided with a power frame 7; the power frame 7 is provided with a driving motor 8 connected with a control circuit, and one side of the power frame 7 is provided with a driven shaft 9 through a bearing. One end of the driven shaft 9 is connected with the output end of the driving motor 8 through a gear transmission, the output end of the driving motor has a driving gear, the end of the driven shaft has a driven gear meshing with the driving gear, and the driven shaft 9 is provided with a winding drum 10 for winding the rope and a cam block 11. As shown in the accompanying Figure 3 The winding drum can wind or lower the rope, and the end of the power frame 7 is provided with a side branch 12, the inner side of the side branch 12 is provided with a control button 13 connected with the control circuit, and the control button 13 is in abutting engagement with the cam block 11; one end of the rope on the winding drum 10 is connected with a lifting frame 14, as shown in the accompanying Figure 4As shown, the lifting frame 14 is connected with the protective sleeve 15 through the fixed rope. The signal output end of the control button is connected with the control circuit, which is responsible for converting the physical pressing signal into an electrical signal to drive the power supply end and the forward and reverse control end of the motor, which are also electrically connected with the control circuit to receive the driving instructions output by the control circuit. At the beginning of the exercise, the driving motor drives the driven shaft to rotate through the gear transmission, and the winding drum on the driven shaft synchronously recovers the rope to lift the lifting frame and the protective sleeve to support the mother's hips. At this time, the cam block rotates with the driven shaft, and is not in contact with the control button. The control circuit maintains the motor in the forward rotation state until the mother's hips reach the high point. When the cam block is rotated to a certain angle (corresponding to the high point position of the hips) by the driven shaft, the protruding part of the cam block abuts against the control button inside the side support, and the control button transmits the trigger signal to the control circuit. The control circuit immediately switches the current direction of the driving motor, instructing the motor to change from forward rotation to reverse rotation. When the motor reverses, the winding drum releases the rope, and the mother's hips gradually descend. The cam block continues to rotate with the driven shaft. When the protruding part of the cam block is separated from the control button (corresponding to the hips falling to the low point), the control button resets and transmits a reset signal to the control circuit. The control circuit again switches the current direction, instructing the motor to resume forward rotation. The stand 5 is a telescopic rod structure. The stand adopts a telescopic rod, and the stand mainly has a fixed rod and a movable rod. The movable rod and the fixed rod are connected by a bolt, and the position of the movable rod is determined by inserting the bolt.

[0020] One end of the top cross bar 6 has a fixed pulley 22, and the rope on the winding drum 10 is wound around the fixed pulley 22. The fixed pulley is installed at one end of the top cross bar, and its core function is to change the force direction of the rope. When the driving motor drives the winding drum on the driven shaft to rotate, the tension direction of the rope generated by the winding drum is originally along the tangent direction of the winding drum. However, the lifting frame needs to be lifted vertically (or along the vertical track that matches the movement of the mother's hips) to support the hips.

[0021] The lifting frame 14 includes a frame body 23 connected with the rope. The upper end of the frame body 23 has a rope connector 24 connected with the rope. The end of the frame body 23 has an extension rod 25. The extension rod 25 has connecting holes 30 at both ends for connecting the fixed rope. The fixed rope at the end of the extension rod is connected in the connecting hole, and the other end of the fixed rope is connected with the protective sleeve. At this time, the fixed rope is in a diagonal pulling state. The length of the extension rod expands the fixed rope diagonally, avoiding the influence of the fixed rope on the mother during exercise. The end of the extension rod 25 is connected with the fixed rope, and the end of the fixed rope has a lock catch 26 connected with the protective sleeve 15. The protective sleeve is connected with the fixed rope through the lock catch. Before exercise, you only need to align the lock catch with the ring on the side of the protective sleeve and gently buckle it to achieve stable connection. After exercise, press the lock catch to unlock the rod to quickly disassemble it, which is convenient to operate.

[0022] The protective sleeve 15 comprises a waistband 27, the middle part of which is connected with a crotch belt 28, and both sides of the waistband 27 are provided with a loop 29 for connecting a lock 26, as shown in the accompanying drawings. Figure 5 The waistband is connected by a Velcro structure, and the material is a cotton and ammonia blended fabric combined with a medical-grade elastic fiber. The cotton and ammonia composition ensures skin-friendliness and breathability, avoiding skin heat and allergy caused by long-term wearing, and adapting to the characteristics of increased skin sensitivity during pregnancy. The medical-grade elastic fiber gives the fabric high resilience, allowing it to stretch flexibly with the abdominal bulge and hip movement, ensuring a snug fit without tightness and compression, and also providing excellent anti-deformation ability, preventing relaxation during long-term use.

[0023] The working principle of the present application is as follows: the pregnant woman wears the protective cover 15 on her body, adjusts the tightness through the magic tape of the waistband 27, buckles the lock 26 at the end of the fixing rope with the ring sleeves 29 on both sides of the protective cover 15, and ensures the stable connection of the fixing rope and the protective cover 15; the pregnant woman kneels on the symmetrical knee supports 33, fixes the legs through the magic tape binding belt 18 of the base 16, and the leg is blocked from sliding forward by the baffle 17 at one end of the base 16; the pregnant woman holds the main rod 19 of the hand support frame 44 with both hands, the lateral support rod 21 enhances the stability of the main rod 19, helps the pregnant woman to offset the problem of forward displacement of the center of gravity during pregnancy, and avoids body shaking during exercise; the driving motor 8 is started, the motor output end drives the driven shaft 9 to rotate through the meshing transmission belt, the driven shaft 9 synchronously drives the rotating of the winding drum 10 on it, and the winding drum 10 starts to recover the rope; the rope recovered by the winding drum 10 drives the whole lifting frame 14 to rise through the rope connecting piece 24 of the lifting frame 14, the extension rod 25 at the end of the lifting frame 14 transmits the pulling force to the protective cover 15 through the fixing rope, and forms an upward supporting force on the hips of the pregnant woman, under the assistance of mechanical support, the pregnant woman actively performs the lifting exercise, independently contracts the pelvic floor muscle, controls the hips to rise upward synchronously with the lifting frame 14, and in the process, the pregnant woman needs to actively perceive the contraction state of the pelvic floor muscle, adjust the contraction strength and rhythm, when the driven shaft 9 drives the winding drum 10 to continuously recover the rope, the cam block 11 on the driven shaft 9 synchronously rotates to a specific angle, the protruding part of the cam block 11 abuts against the control button 13 inside the end side branch 12 of the power frame 7, the control button 13 transmits the high point trigger signal to the control circuit by pressing the control button 13, and the circuit immediately switches the rotating direction of the driving motor 8; the motor reverses to drive the driven shaft 9 and the winding drum 10 to reverse rotation, the winding drum 10 starts to lower the rope, the supporting force of the protective cover 15 on the hips gradually decreases, the pregnant woman actively controls the pelvic floor muscle to relax, and cooperates with the slow falling back of the hips; when the hips of the pregnant woman fall back to the preset low point, the driven shaft 9 drives the cam block 11 to continue to rotate, the protruding part of the cam block 11 is separated from the control button 13, the control button 13 is reset and transmits the low point reset signal to the control circuit; the control circuit switches the rotating direction of the motor again, the motor restores the forward rotation, the winding drum 10 recovers the rope again, and enters the next cycle until the exercise is completed.
